Global Majority of State Parties Now Signed onto the Treaty on the Prohibition of Nuclear Weapons

On September 26 th , 2025, during the United Nations General Assembly in New

York City, the Republic of Ghana ratified the Treaty on the Prohibition of Nuclear

Weapons (TPNW), and the Country of Kyrgyzstan signed on. With these actions, a

global majority of countries have signed onto the United Nations nuclear weapons ban

treaty. A total of 99 out of the 197 eligible states have taken legal action - 74 have

ratified and 25 have signed. Such action sends a strong message to the nuclear-armed

states and their allies that they are now the minority and irresponsible actors threatening

global security.
